A testicular mass found to be a rare testicular adult-type granulosa cell tumor: A case report and literature review

Introduction and importance: Granulosa cell tumors (GCTs) are rare tumors, which mostly affect the ovaries. GCTs are classified into two types: juvenile and adult. Adult testicular GCTs are potentially malignant sex cord-stromal tumors. Case presentation: Here, we report a case of a 63-year-old man who presented with a right testicular nodule. Testicular ultrasound showed a hypoechoic tissue mass, measuring 3 cm and hyper vascularized in the color Doppler. A radical orchidectomy was performed. Histology showed a typical adult-type Granulosa cell tumor. After 12 months follow up, the patient is doing well and disease-free. Clinical discussion: According to our case and a review of the literature, this type of tumor is an uncommon and slow-growing neoplasm. The diagnosis is confirmed by histology, treatment is based on surgery, radical orchidectomy. Long-term follow-up of patients is essential because distant metastases may emerge late in the clinical course. Conclusion: This case report adds valuable insights to the limited literature on adult testicular Granulosa cell tumors. Radical orchidectomy remains the optimal treatment, and early diagnosis, coupled with surgery, significantly enhances prognosis.
